Airtable is a powerful and flexible tool for storing and organising information. I've used it to compare email marketing tools and outbound sales tools, and much more. I have started using Airtable to store and organise quotes from books, articles and talks that I want to refer to in the future.
The format is simple – I am noting the quote, the author, the source and a link (where available). I also tag each quote with keywords so I can filter and sort them as needed.
You can take a look at the full database here.
I have grouped the quotes by keyword – but this is just one of the ways the quotes can be ordered. If you would like to do something similar you can sign up to Airtable for free, and use my database as a template to get you started.
